Beta 7: Location of an Earth Alliance colony and prison. John Clemens operated the prison system during the Earth Alliance Civil War, in which it is assumed that he was responsible for the murder and torture of Clark regime dissidents.[12] One of the colony's former chief of security was compared to Zack Allan by Trace, a small time gangster and former resident on the Beta VII colony. Trace took credit for consecutively assassinating at least two of the colony's security chiefs.[13]

Brensil IV: The fourth planet of the Brensil System. Little more than a barren rock, Brensil IV was home to a number of mining colonies and small settlements. By 2258, the mine had closed and those with ships had left, leaving what remained on the verge of total abandonment.[17]

Bricarn IX: A border world at the edge of Centauri space. In 2274 Bricarn IX was one of several defenceless but strategically valuable planets attacked by the Centauri Republic as part of a campaign of increased belligerence towards the Interstellar Alliance.[18]

Cygnus IV: A relatively unappealing planet and the location of a factory and power plant, privately owned by a particularly eccentric human. In the mid-2260s and unknown ship crashed on Cygnus IV. Lou Welch while working security at a nearby power plant investigated the wreck and discovered a piece of technology he would later call his "invisibility cloak".[23][24]

Dorak VII: Location of a small Shadow base located only 10 light-minutes from one of the Shadows' main staging areas. On January 23, 2261, the base was destroyed by five ships from the Army of Light lead by White Star 14. The attack was a cover to allow the Shadows to capture or destroy White Star 14 and obtain false intelligence that would ultimately draw them into the Battle ofCoriana VI.[32]

Fensalir: UTC43-02C, a Class 4 Planet. In January 2259Catherine Sakai surveyed the world for Universal Terraform looking for Quantium 40. Although the initial robotic probe detected signs of with diridium gas in the atmosphere (a possible indication of Q-40) Sakai's geological survey showed the planet was an "FGP" (Fool's Gold Planet) containing no significant quantities of Quantium 40, despite looking promising in an initial scan.[8]

Harper's World: A border world at the edge of Centauri space. In 2274 Harper's World was one of several defenceless but strategically valuable planets attacked by the Centauri Republic as part of a campaign of increased belligerence towards the Interstellar Alliance.[18]

Immolan V: Colony world of the Centauri Republic. One of the Republics centres of tourism and is open to many of the other races. Of particular note is the colony's temple to Gon, widely recognized as the most beautiful building ever constructed by a sentient race, and each year draws both pilgrims and tourists in their millions.[1]

Kazomi VII: Kazomi VII was a colony in Sector 498.[26] During the Vorlon offensive in 2261, Kazomi VII was one of several colonies to take on survivors and refugees from the planets that had been destroyed by the Vorlon planetkiller.

Kitab III: Site of a Yolu colony, located in a system neighbouring the Yolu home system.[1]

Mipas: Homeworld of the Mipasians. Originally located just outside of the Freehold, the planet fell under the jurisdiction of the Drazi Freehold shortly after the Drazi discovered valuable mineral deposits and reconfigured their borders to incorporate Mipas.[45] In 2274 Mipas was one of several defenceless but strategically valuable planets attacked by the Centauri Republic as part of a campaign of increased belligerence towards the Interstellar Alliance.[18]

Morbis: An independent Centauri colony on the border of the Republic. In the mid-to-late 2260s, Morbis was one of half a dozen or so outlying worlds taken over by the Prime Candidates as part of MinisterDurla's covert military build-up and used as the site for a secret munitions plant disguised as an educational facility.[47] In January 2271, Morbis was one of the first targets to be bombed by the Centauri resistance movement under the direction of Ambassador Cotto.[48]

Nefua: An independent Centauri colony on the border of the Republic. In the mid-to-late 2260s, Nefua was one of half a dozen or so outlying worlds taken over by the Prime Candidates as part of MinisterDurla's covert military build-up and used as the site for a secret weapons development centre disguised as a health facility.[47] In January 2271, Nefua was one of the first targets to be bombed by the Centauri resistance movement under the direction of Ambassador Cotto.[48]

Shambah III: Location of a Drazi colony. The primary food production centre for the Drazi Freehold, Shambah III has been extensively terraformed for land and sea farming.[1]

Shandukan: A border world at the edge of Centauri space. In 2274 it was one of several defenceless but strategically valuable planets attacked by the Centauri Republic as part of a campaign of increased belligerence towards the Interstellar Alliance.[18]

Tarkon III: Planet visited by the Excalibur in 2267. A survey of the planet showed no survivors.[46]

Tau Ceti IV: Tau Ceti IV was the site of the Earth Alliance's newest colony following the Earth-Minbari War. Established in 2249 on the borders of Narn and Centauri space, the colony serve as a trade centre between the Alliance and those races. Consisting of only a single domed city and a couple of research outposts, it is a rough environment and was still considered a frontier world as late as 2261.[1]

Tizino Prime: Location of a colony in Sector 498.[26] During the Vorlon offensive in 2261, Tizino Prime was one of several colonies to take on survivors and refugees from the planets that had been destroyed by the Vorlon planetkiller.

Vermini VII: Planet on the border of Drazi and Brakiri space. In September 2262 a brief skirmish broke out over a visit by some Brakiri pilots to a primarily Drazi brothel, upsetting the Drazi pilots due to some taboo about touching Brakiri.[57]

Viscus IV: Planet that suffered a drought at some point prior to 2258. The techno-mageKell provided assistance in feeding the many victims of that cataclysm, a feat that was lauded by his fellow techno-mages as being among the greatest achievements in his long life.[58]

Zafran VII: Prior to the convocation of 2258, the techno-mageKell made his home on Zafran VII, and became an advisor to the Shan of Zafran VII.[17] In 2261, a salvage merchant called Isaac claimed to have found an abandoned Starfury floating dead in Sector 87. He later sold parts of it to a trader on Zafran VII.[59]

Zafran VIII: Located adjacent to Zafran VII, the techno-mageBurell made her home on Zafran VIII. The planet is something of a backwater as it is located on a marginal hyperspace route that connects systems off the beaten track.[17]
